分别从理论和实验上研究了截头三角形银纳米棱镜的光学性质及其对铕配合物Eu（TTFA）（3）荧光的影响。理论上，我们发现这些纳米棱镜对Eu离子的荧光有很大的增强作用，其增强因子与纳米棱镜的浓度有关。并在实验中得到了验证。研究了银纳米棱镜对Eu离子辐射和非辐射衰减速率的影响，发现银纳米棱镜大大降低了非辐射衰减引起的能量损失。(C)2011年美国光学学会
The optical properties of truncated triangular silver nanoprisms and their influences on the fluorescence of europium complex Eu(TTFA)(3) were investigated in theory and experiment separately. In theory, we found that the fluorescence of Eu ions would be greatly enhanced by these nanoprisms, the enhancement factor of the fluorescence depended on the concentrations of nanoprisms. They were verified in the experiment. The influence of silver nanoprisms on the radiative and nonradiative decay rates of Eu ions were also deduced, and found that the silver nanoprisms greatly reduced the energy loss caused by the nonradiative decay.
